SEATTLE & SAN DIEGO--(BUSINESS WIRE)--Calypso Medical Technologies, Inc., a developer of real-time localization technology used for the precise tracking of tumor targets, today announced it will showcase Dynamic Edge™ Gating Technology, recently cleared by the U.S. Food and Drug Administration, at the 52nd Annual Meeting of the American Society for Radiation Oncology (ASTRO), now underway at the San Diego Convention Center. This latest innovation of the Calypso® System automates the response to organ motion that occurs during the delivery of radiation to prostate cancer tumors in order to protect healthy tissue from unintended radiation. Demonstrations will be available at the Calypso booth (number 1236) as well as the Varian Medical Systems booth (number 201) and Siemens Medical Solutions booth (number 2715). Dynamic Edge Gating Technology extends the Calypso System’s safeguard against unnecessary radiation and complements ASTRO’s Target Safely initiative announced earlier this year in response to public concern over excessive radiation delivery caused by equipment and operator error.
